King Charles III and the Queen Consort will pay a visit to Wales on Friday and attend a service of remembrance for Her Majesty the Queen at Llandaff Cathedral.
They will also meet with local members of the community as part of the itinerary for their trip.
There will be a motion of condolence at the Senedd in Cardiff Bay before the King holds a private audience with Mark Drakeford, the First Minister of Wales.
The meeting will take place at Cardiff Castle, where the first 2,000 people in line will be permitted to enter.
Following his investiture at Caernarfon Castle in North Wales in 1969, Charles served as Prince of Wales for over 53 years.
Dr Mari Wiliam, lecturer in modern history at Bangor University, told Sky News: “It was the big, formal introduction of Charles as this symbol – if you like – of Wales.
“Opinion polls from the late 1960s show about 70 percent to 80 percent approval of Charles being invested as Prince of Wales – but there were also very vocal protests.
“I think in Welsh history we tend to focus a lot on the protest against Charles and not so much on how he tried to integrate himself with Wales and Welsh culture.”
While preparing to take on the role Charles spent ten weeks studying Welsh history and the language at Aberystwyth University, as depicted in Netflix series ‘The Crown’.

Richard Roberts told Sky News in Caernarfon he was “ambivalent” about Charles ascending to the throne,
He said: “I was 13 in 1969 when the investiture took place here and it was in the age when we started to question politics and the situation of Wales within the British Isles, so I’m quite ambivalent.”
When asked if was supportive of the new monarch he responded: “No, not really, because I feel that the establishment does not respect my Wales.”
However royalist Janine Brown said: “I’m glad that he’s got his opportunity to become King, it’s as it should be, obviously in sad circumstances but I think he’ll make a good King.”
